Re: Problem using OVRDBF and ALIAS in a RPG program

I have a program that reads File_A which has multiple members.

There is a CL program before the SQLRPGLE program that does a OVRDBF FILE_A
to member B. In the program, I use a SQL SELECT to total up the balance on
an invoice which is SUMed against member A.

I create an ALIAS - CREATE ALIAS QTEMP/FILE_A_A for LIB/FILE_A(A) in the RPG
program.

In the program, I do a SELECT sum(AMT) from QTEMP/FILE_A_A.

Problem:

When the OVRDBF is used, the SELECT does not find the records. It seems to
be looking at member B in File_A.

When I remove the OVRDBF, the SELCT works as designed.

Does anyone know what the problem is and how to work around the issue?

If I understand it right, you have an F spec and an SQL SELECT that you
want to point to two separate members. OVRDBF does indeed affect SQL as
well as RPG native opens, so what you see is what's supposed to happen.

Way back when (before SQL) I had a similar problem; needed two F specs
pointing to the same file but different members. I did something like:

FFILE_A_A IP
FFILE_A_B UF

OVRDBF FILE_A_A FILE_A MBR(A)
OVRDBF FILE_A_B FILE_B MBR(B)

CALL RPGPGM
